Nach dem Update auf die 4.1er Version ist der Login ins Backend nicht mehr möglich. Jeder Loginversuch führt zu einem endlosen Ladesymbol, was wohl auf den Fehler beim Aufruf von /backend/Login/login zurückzuführen ist: Method „Shopware::PasswordEncoder“ not found failure in Shopware/Components/Auth/Adapter/Default.php on line 218 #0 Shopware/Components/Auth/Adapter/Default.php(218): Enlight\_Application-\>\_\_call('PasswordEncoder', Array) #1 Shopware/Components/Auth/Adapter/Default.php(218): Shopware-\>PasswordEncoder() #2 Zend/Auth/Adapter/DbTable.php(386): Shopware\_Components\_Auth\_Adapter\_Default-\>\_authenticateValidateResult(Array) #3 Enlight/Components/Auth/Adapter/DbTable.php(142): Zend\_Auth\_Adapter\_DbTable-\>authenticate() #4 Shopware/Components/Auth/Adapter/Default.php(109): Enlight\_Components\_Auth\_Adapter\_DbTable-\>authenticate() #5 Zend/Auth.php(117): Shopware\_Components\_Auth\_Adapter\_Default-\>authenticate() #6 Enlight/Components/Auth.php(74): Zend\_Auth-\>authenticate(Object(Shopware\_Components\_Auth\_Adapter\_Default)) #7 Shopware/Components/Auth.php(136): Enlight\_Components\_Auth-\>authenticate(Object(Shopware\_Components\_Auth\_Adapter\_Default)) #8 Shopware/Components/Auth.php(92): Shopware\_Components\_Auth-\>authenticate(Object(Shopware\_Components\_Auth\_Adapter\_Default)) #9 Shopware/Controllers/Backend/Login.php(64): Shopware\_Components\_Auth-\>login('user', 'password') #10 Enlight/Controller/Action.php(148): Shopware\_Controllers\_Backend\_Login-\>loginAction() #11 Enlight/Controller/Dispatcher/Default.php(521): Enlight\_Controller\_Action-\>dispatch('loginAction') #12 Enlight/Controller/Front.php(214): Enlight\_Controller\_Dispatcher\_Default-\>dispatch(Object(Enlight\_Controller\_Request\_RequestHttp), Object(Enlight\_Controller\_Response\_ResponseHttp)) #13 Shopware/Components/HttpCache/HttpKernel.php(79): Enlight\_Controller\_Front-\>dispatch() #14 Symfony/Component/HttpKernel/HttpCache/HttpCache.php(434): Shopware\Components\HttpCache\HttpKernel-\>handle(Object(Symfony\Component\HttpFoundation\Request), 1, true) #15 Shopware/Components/HttpCache/AppCache.php(234): Symfony\Component\HttpKernel\HttpCache\HttpCache-\>forward(Object(Symfony\Component\HttpFoundation\Request), true, NULL) #16 Symfony/Component/HttpKernel/HttpCache/HttpCache.php(230): Shopware\Components\HttpCache\AppCache-\>forward(Object(Symfony\Component\HttpFoundation\Request), true) #17 Shopware/Components/HttpCache/AppCache.php(99): Symfony\Component\HttpKernel\HttpCache\HttpCache-\>pass(Object(Symfony\Component\HttpFoundation\Request), true) #18 Shopware/Bootstrap.php(70): Shopware\Components\HttpCache\AppCache-\>handle(Object(Symfony\Component\HttpFoundation\Request)) #19 Enlight/Application.php(192): Shopware\_Bootstrap-\>run() #20 shopware.php(83): Enlight\_Application-\>run() #21 {main} Bei Google finde ich zu dem Fehler einen Eintrag auf GitHub, der vom September letzten Jahres ist und jetzt nicht mehr zu erreichen ist. Kann jemand helfen?
